When my wife did it, there was no line. She even downloaded the form from the internet and filled it out before getting there.
With the DMV, you just need to know what you are doing. Don't go in the last week of the month, don't go in later in the afternoon, don't go in on a Friday, and don't go in just as it opens. Follow those rules (especially the last week of the month rule) and you'll have much shorter lines.
